Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact between the ball and the material.

SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.

further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density.
